Because he's a weak PM who is more concerned about his own popularity which stops him from making the tough decisions you need in times like this .
It's difficult to believe anything he says because he is a career liar and an opportunist .
Almost every position he's held he's made a complete feck up of .
He's somehow managed to become PM with a three word slogan and not policies which he avoided to the extreme or to even discuss because he didn't have any .
He's totally unfit to be the PM of this country , Thatcher would have slung him out of the government and you'd never have heard of him again if he'd been around back then .
This country is vast becoming a worldwide joke and it's people like him who are the root cause of it voted in by needy people who are the most willing to be led , historically to tragedy which was Hitler's root to power .
If you want an example of real leadership in a crisis then read the link I've provided , remember that Greece is one of the most hardest hit country's to have endured austerity .... and yet .
